What tends to happen with these sort of posts is that you get both parents and childfree people becoming increasingly defensive about their decisions. It doesn't mean either are wrong, just that there are some twats in both camps who like to start an argument.
No one can make the decision other than you and your partner, if you have one.
I know a lot of parents will say that only they know both sides of the fence because they were childfree too...yeah, but in my case, the last time I was childfree was 24 years old, just married and still wanting to go clubbing and holidaying in Ibiza every summer. Even if I hadn't had kids I wouldn't have that lifestyle now at 51 so it's stupid to assume that a childfree person my age is doing the things I did before children.
I also think that a lot of parents have rose tinted specs when they think about what they would have done without kids. In my childfree fantasy world I wouldnt have quit my PhD and would have become a scientist of international renown. The truth is, I would have made the same choices as I actually made and ended up as an NHS manager.
I don't mind admitting that I had a child because it was the next thing to tick off after getting married. There wasn't a lot of thought put into it, it was just something we did. I always assumed I'd have kids because that was what we all did. And this was only 25-30 years ago, not the dark ages. If I'd stopped and thought about it, I'm not sure I would have had them at all. While I adore them, of course, I'm not a maternal person and I struggled with becoming a mother and the loss of identity, the boring drudgery and basically everything to do with parenthood. I wish I'd stopped and thought about what I really wanted from my life instead of ticking off the next box on the to do list of life.
I think that if you have a good life now and feel content with it, don't have a child.
